[ARC5] Antenna for small yard

[AKLDGUY .]

Can anyone suggest a suitable antenna for 80m designed for low impedance
transmitters such as the BC-230 and ARC-5?

My yard is 24 feet (7.2m) x 12 feet (3.6m) with a 5 foot (1.5m) high wooden
fence on three sides. The ground is covered with concrete pavers, so
burying wires is not an option. I do not want to erect poles, so the fence
will be the only support.

I have a 2m J-pole mounted out on the fence with RG-213 coax dropping down
and running across to the door. I figured that this might act as "the body"
of a plane, so I disconnected the coax from my 2m transceiver and connected
the braid to the Ground terminal of the BC-230.

Then I ran out a wire from the BC-230 antenna terminal out to the fence
very close to the J-pole. This wire was about 4 feet high, and I figured
that the whole thing might approximate a short antenna above a plane body.
Unfortunately, no antenna current was indicated on the BC-230's RF ammeter.
It normally shows about 0.6 Amp when operated into a 5 ohm dummy load in
series with 150pF (ARC-5 transmitter cap).

Is anyone able to model that entire thing as an 80m antenna, or can anyone
suggest a better arrangement?
